Polymerization inhibitors, such as MEHQ
This collaboration continues to provide Samsung's customers with services that meets the needs and tastes of all music lovers on the move," said Neeraj Seth, Marketing Manager -- Mobile Phones, Samsung MEHQ
The dilution of the sample with cold water, the adding of MEHQ and oxygen as an inhibitor system will stop the reaction in the gap.
Thus radicals are not available to activate the monomers as long as oxygen or rather MEHQ is within the solution.
It can be summarized that there is a strong dependence of the induction period on the concentration of initiator and a weaker dependence on monomer, because the concentration of oxygen and MEHQ is proportional to the monomer content.
Glycidyl methacrylate (GMA; 97%, contains 100 ppm monomethylether hydroquinone as an inhibitor), 1,3-butanediol dimethacrylate (BDDMA; 99%, contains 150-250 ppm MEHQ
as an inhibitor) and divinylbenzene (DVB; 80% contains divinylbenzene, ethylstyrene, 4-butylpyrocatechol), pullulan ([M.
